Doesn't look lik Pinba issue to me, the backtrace clearly leads to Protobuf. Does it even work when compiled with clang? I don't know. Why don't you try GCC instead?

ghost commented 12 years ago

test gcc, but protobuf.. your extension crash

comment - ;extension=pinba.so - work fine all

tony2001 commented 12 years ago

Пересобирал GCC что? Экстеншен или Protobuf? Проблема явно в Protobuf + FreeBSD, у других всё прекрасно.

ghost commented 12 years ago

еще бага в порте

make install clean

===> php5-pinba-2011.08.18 cannot install: doesn't work with PHP version : 5 (Doesn't support PHP 5). *\ Error code 1

Stop in /usr/ports/devel/php5-pinba.

tony2001 commented 12 years ago

Ок, я в ближайшее время переделаю экстеншен на protobuf-c вместо либы на С++. Насчет порта - к сожалению, без понятия что там и почему оно не поддерживает php5.

ghost commented 12 years ago

на "Си" будет по феншую, спасибо!

tony2001 commented 12 years ago

Готово. В бранче protobuf_c теперь С-шная версия, без зависимости от libprotobuf.

ghost commented 12 years ago

да все отлично теперь все собираеться и работает, хотя php-клиент стал чуть дольше запускаться

tony2001 commented 12 years ago

есть какие-то детали? что значит начал дольше запускаться? он же при старте ничего не делает, только при request shutdown.

ghost commented 12 years ago

в общем protobuf_c отлично пашет, можно мэйнтейнером в порты запилить
